Before · Isaiah 6:2–3
2Above him stood the seraphim. Each one had six wings. With two he covered his face. With two he covered his feet. With two he flew. 3One called to another, and said, “Holy, holy, holy, is the LORD of Armies! The whole earth is full of his glory!”
4The foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke.
After · Isaiah 6:5–6
5Then I said, “Woe is me! For I am undone, because I am a man of unclean lips and I live among a people of unclean lips, for my eyes have seen the King, the LORD of Armies!” 6Then one of the seraphim flew to me, having a live coal in his hand, which he had taken with the tongs from off the altar.
